Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1, a device for rapidly replacing a carrier roller comprises a base 1, a lower screw rod 2, an adjusting sleeve 3, an upper screw rod 4 and a supporting ejector rod 5.
Connection relation: the bottom end of the lower screw rod 2 is fixedly installed in the middle of the base 1, the upper portion thread of the lower screw rod 2 is sleeved inside the lower end of the adjusting sleeve 3, the lower portion thread of the upper screw rod 4 is sleeved inside the upper end of the adjusting sleeve 3, and the supporting ejector rod 5 is connected to the upper end of the upper screw rod 4 through a pivot with the angle adjustable through an angle adjusting seat 6.
Wherein, the base 1 is a cross positioning groove seat and is positioned in an anti-rotation way through a cross bottom groove of the base 1. Preferably, the cross-shaped positioning groove seat is formed by welding channel steel.
Wherein, the screw thread setting on lower screw rod 2 and the 4 peripheral faces of upper screw rod makes adjusting sleeve 3 rotate, and lower screw rod 2 and upper screw rod 4 are close to each other or are kept away from each other to realize the regulation of high flexible. Preferably, the external threads of the upper screw 4 and the lower screw 2 are in the form of lead screws.
Wherein, adjusting sleeve 3 includes barrel 31 and the end cap 32 of setting at barrel 31 both ends, sets up the internal thread that matches with the external screw thread of lower screw rod 2 and last screw rod 4 on adjusting sleeve 3 inner wall, and two end caps 32 spiro union are at the both ends of barrel 31. Preferably, the end cap 32 is a nut and is screwed on the external threads formed on the outer sides of the two ends of the cylinder 31 through threads.
In order to adjust the height conveniently, set up adjustment handle 33 on the outer wall of adjustment sleeve 3, the welding of two symmetry of adjustment handle 33 is in adjustment sleeve 3 middle part.
